MACHINE Foa 'CLEANING COTTON-SEED.

SPECIFICATION forming part of Letters Patent No. 377,621, datedvPebruary 7, 1888. Application tiled May 26, 1887. Serial No. 239.4634.` (No model.)

Y TonZZ whom it may concern:

Beitknown that I, HENRYEDWARD KNRRR, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and useful Machine for Cleaning GottonSeed, of which the following is a specification.

The object of my invention is to remove 1 the adhering cotton-lint from the cotton-seed which has not been removed by the cottongin, and which it is desirable to remove before going into a heater and oil-press. I attain this objectby the mechanism illustrated in the accompanying drawings, in which- Figure l is a vertical section of my improved machine, a portion of the fan-blades being broken away; Fig. 2, a plan view, a portion of the casing being broken away.

Similar letters refer tol similar parts in the several views.

My machine consists of a stationary casing, a, made either of wire-gauze or of perforated metal, with a spout, b, for admitting cottonseed, and a spout, c, for discharging same. In-

side of the casing a is a revolving parallel cylinder, M, open at both ends. This cylinder is constructed as follows: Two heads, d and e, are fastened to a shaft,f, which shaft has a driving-pulley, g. Between these. heads are fastened a number of vertical bars, h, leaving spaces between said bars.

The open parallel cylinder M is set in rapid4 motion and seed vdropped into b. The loose end of the brushes i is by centrifugal force and the action of the forced air thrown against the casing c, the cotton-seed is dragged around with it, and by rubbing against a and from the action of the brushes c' the seeds lose all their lint asthey gradually descend and are nally discharged through spout c. The wings'K act as fans and discharge air -through the space between h and z', which keeps Vthe seed cool.

The other end rests loosely on the (Not shown After the seed and lint come out of spout c they are separated by a current of air in the usual manner. .v

The cotton-seed with the linton whenit first enters the machine occupies they, largest space between the fixed ends of the brushes t' and the perforated casi ng a.' The perforations inthe casing a retard the forward and downward motion of the seed somewhat, so that as the seed rotates the lint begins to be removed,

and as the bulk is reduced the seedworks forward and downward in the angular spaces toward the points of the flexible -brushes i, un-

til the seed is finally cleaned of all the lint.

The air being drawn in at ends of the rotating cylinder M is forced by the fanning action of' the arms K outwardly against the backs of the brushes i, as shown by the arrows. Thus a constant spring-like pressure is maintained blades K, the brushes z', having flexible backs. and secured atoneend to the bars h, and the perforated stationary casing a, substantially as shown and described.

2. In combination with the stationaryperforated casing a, the cylinder M, rotatingl therein and consisting of the` open heads d e,

the. vertical ybars h, arranged between said Y heads, as shown, and the fan-blades K ofthe brushes i, having iiexible backs, each of said brushes having one of .its ends secured to one of the-bars h, and its other end overlapping the adjacent bar h, the free ends of said brushes being thrown out against the perfo,-y

rated casing a by centrifugal force and an airblast, substantially in the'manner shownv and described.
